Hi,

I have a property Status in @baseclass but i need a property status as my json in rest-connect rule is expecting it.

I couldn’t create status property as it is already there in baseclass and it’s throwing this error.

**This record has 2 Errors in 2 places**

**pyPropertyName—**

**A case mismatch has been found for this property: ‘status’ doesn’t match ‘Status’**

**Error—**

**Definition required to confirm to Data-.Status instance created 20181213T073945.991 GMT**

I tried property qualifier but that didn’t work.

Kindly help.

Thanks

@SaiM8658 As mentioned in the link above Did you try creating the status property with a different name like “statusInt”? else you can delete the existing property and create a new one with the same case

HI @SaiM8658,

**JSON is case-sensitive**.

While mapping the JSON data to the Pega clipboard, JSON Key must be matched with the Pega property.

As the JSON key is **status** then it will expect the same **status (case sensitive)** property in Pega as well.

Please try to create a property **status** then it will work.

Regards,

K Chandra Prakash.

@SaiM8658

I created property - qualifier in the same class of results page from service and the issue is solved.

Qualifier used - pzExternalName

Thanks
